The Baltimore Sun will take a look at all 13 of the Ravens' 2010 opponents. Today's early scouting report is on the Pittsburgh Steelers, the Ravens’ opponent in Week 4 and Week 13:

Head coach: Mike Tomlin (9-7 overall record)

2009 record: 9-7

Biggest addition: Bringing in Byron Leftwich to become the starting QB for at least the first quarter of the season. Ben Roethlisberger has been suspended for at least the first four games of the season for violating the league’s personal conduct policy. If this change doesn’t turn the Steelers into a run-heavy offense again, nothing will.

Key loss: Trading away WR Santonio Holmes. He was shipped because the Steelers didn’t want to deal with another player being suspended. It was good for the image of the franchise. It was bad for the offense, which lost its best playmaking wide receiver.

Question mark: Who plays right tackle for the Steelers? Willie Colon is suddenly out for the season with a torn Achilles' tendon. The Pittsburgh Post-Gazette suggests that Pittsburgh will replace him with Jonathan Scott, who started eight games last season for the Buffalo Bills. The Steelers have also met with Flozell Adams, the former Dallas Cowboys lineman whose play has declined over the past few seasons.

Projected 2010 finish: 8-8, second in the AFC North. This just doesn’t seem to be the Steelers’ year, from the suspension of Roethlisberger to the trade of Holmes to the season-ending injury to Colon. Breaking even should be considered a success.
